I said "typically"...yes there are high-end devices that include gyros as well (or will...did you notice the date on that article). Until you get the sensor and optics to match, there's little reason to go that route solely for the purpose of photography since accelerometers can do a pretty fine job by themselves. On a phone like the N86 with its 8MP camera (obviously being marketed towards the photography crowd) or actual single-purpose digital cameras...maybe it would be worth it. On the N900...probably not so much given it is expensive and crowded enough as-is. In any case, one would be FAR better off overall with a more sensitive accelerometer (far more general-purpose) than just throwing in a gyroscope when space and power are limited. /shrug maybe some engineers think the tradeoff is worth it if the price is right.

The only thing a gyro can truly do is add a marginal improvement in performance over an accelerometer in some cases. It doesn't add anything "new" worth talking about in a phone platform. If you are willing to pay more, have less battery life and/or have an even chunkier phone for that marginal improvement in pointing accuracy or image stabilization...then go for it. However, I'd wager 99% of the consumer market out there (myself included) is quite happy with the performance modern solid-state accelerometers can give when coupled with decent software (wii controller being a fine example..yes it can be and was improved later, but it was incredible as-is too). If they get down to next-to-free in terms of actual dollar cost, space requirements, and power draw..then sure...throw them in. At that point why not? As it is, there's just not enough margin of improvement to make it worth it for the vast majority of the consumer phone market.

So again..what else you got?
